I had imagined an isotropic multi-anchored playsail:
This looks like the figure 1 which is reproduced on https://forum.awesystems.info/t/advanced-kite-networks/2105/7:
But for my idea there were no crosswind kite(s), only a squared area (a round area would had been really an isotropic shape) towing on the anchors in yo-yo mode, perhaps by short strokes, with the winches acting the respective generators, and having springs for tether recall.
I still wonder how a crosswind flight would be achievable and efficient by all wind directions, even by considering that each crosswind kite can be piloted to go everywhere, pivoting on its own mesh of the net, not to mention the complexity of the control in case it works as expected. @AweEnthusiast have you an answer about this?
